How did the Treaty of Yandabo bring Assam under British rule?

The Treaty of Yandabo, signed in 1826, concluded the First Anglo-Burmese War and served as the catalyst for British control over Assam. During the conflict, British forces successfully drove out the Burmese invaders who had occupied the region.12

Following the treaty, the British established administrative control over Assam by appointing a British agent to represent the governor-general. This transition toward full integration proceeded in stages:1

• 1838: Assam was incorporated into British-administered Bengal.1
• 1842: The entire Brahmaputra valley was brought under British rule.1
• 1874: A separate province of Assam was created, governed by a chief commissioner and headquartered in Shillong.1

The treaty effectively ended Burmese influence in the area, allowing the British to consolidate their authority and expand their colonial administration across the region.12
